With compactness MPCB provides high-performance short-circuit current breaking

Wide range of current adjustment dial for optimum protection
Stand-alone motor protection
With Single phasing protection
All accessories are common for both frames and separate short circuit alarm is also available
Padlocking features available on MPCB rotary knob and rocker type

Procedure for selecting the appropriate model:

Confirm the motor full load current

Three-phase load

Single-phase load

For applications in a single-phase

circuit, connect the 3-poles in series

Select the rated current of MPCB

Select the branch circuit cable & confirm the control panel specifications

Confirm the short-circuit current of the circuit

Select the operating characteristics

Long-time operating type or quick
operating type thermal overload relay desired

Same characteristics as desired

for a standard thermal overload relay

Adjustable thermal magnetic trip type MPCB

MOG-S1, MOH-H1, MOG-H2

Instantaneous trip type MPCB

MOG-H1M, MOG-H2M

Note: Please contact the nearest branch office for fuseless type 2 co-ordination selection chart.

We recommend the use of :

1. Line Contactor : This will isolate and protect the soft starter SCR's
from any voltage transient while it's not in operation.
2. Bypass Contactor (For models without built-in bypass) : This will
bypass and protect the soft starter SCR's while in running state from
Current and Voltage transient's.
3. Semiconductor fuses : This will protect the starter SCR's during
starting and stopping states from current transient's and excess IT.

Features of etaSYS:
l

IP 42 panels

Standard GA drawing readily available

Wide range of ratings (35 to 500 kVAr) covers the typical

requirement of APFC panel ratingsfor most of the industries

All the panels are with optimal number of steps and step sizes
- Offers sufficient step resolution which would be suitable for
all types of industries
- Panel operation without hunting of capacitors

Pre-selected switchgear with accurate ratings offers reliable

operation, protection and isolation
Accurate combination of capacitor and reactor offers better
protection against harmonics
Notes:
- Standard lead time of APFC panels is 6 to 8 weeks (Ex-Nagpur)
- Freight charges at actuals
- For other ratings and specifications, contact nearest branch office

The Full Load Current (FLC) indicated for 3-phase motors are of 'squirrel-cage Induction motors' at full load.
Contactors / S-D-Fs indicated are of the minimum ratings. Higher rating of contactors and S-D-Fs can be used.
Selection chart is for standard 3-phase, squirrel cage motor with average power factor and efficiency.
Selection is valid only for complete L&T combinations.
Compliance to Type '2' co-ordination is not assured in case these combinations are changed to accommodate another brand / rating of
products like S-D-F / Fuse etc.
All S-D-F ratings are AC-23A as per IS/IEC 60947-3, IEC 60947-3 & EN 60947-3
Normal motor starting time (<=5 Sec) is assumed. Selection for motors with longer starting times can be made available on request.
These charts remain same for IE1 and IE2 motors
For Type 2 charts for fuseless feeders, kindly contact the nearest branch office.
